In the various figures of the drawings parts have been omitted and otherparts broken away to more clearly illustrate other portions ofthe-structure.

subject-matter of the present invention are shown in their applicationlto that t e of machines which is known as the Yost machine, thoughobviously some of the features of invention may be applied to anycharacter of type-writing machines wherein they may be found available.Referring now to the drawings, 1 indicates the frame of the machine,which supports a type-ring 2, provided with radial slots 3 for thereception of arms or drivers 4, each driver having a hook-likeprojection 5, which bears upona fulcrum-ring 6, arranged in a groove inthe type-ring or support 2. One end of each driver is pivotallyconnected at 7 to a tylpe' bar or carrier 8. A guide-link 9 is pivotal yconnected at 10 to another portion of said type bar or carrier, and saidguide-link is formed at its pivotal end with a or b .plates 124 and 13,suitably and supported centrally of clamped together the type-barsysrlage-feed mechanism. Fig. 18 is adetail The improvements which'constitute the' 33 are enlarged horizontal longitudinal sec- 75 ing theplaten-frame to the carriage, the sec'- IOO disk-like portion 11,whichisheldinrecesses earings formed by a pair of circular 'ring 2.

tem. The faces of the types 14 on the 'various type-bars normally restagainst an inking-pad 15, which is supported on the type- The driver 4of'each type bar or car-y rier is provided with an extension 16, towhich is connected at 16a the upper end of a draw-link or pull-rod 17.The lower endA of each draw-link 17 is operatively connected to abell-crank lever 18, that is pivoted at 19 to a hanger 20, which in turnis secured between clamping-plates 21.

Each driver 4 and the draw-'link 17 thereof is connected by acontractile spring 22 in order to restore the type-bar and its connectedparts to their normal positions. Each bell-crank lever 18 has one armthereof operatively connected at 23 to a draw-link 24, which has ageneral horizontal disposi-` "tion and which is connectedat its oppositeend 25 to an actuating-lever 26,.pivoted at 31 and connected byran arm32 to a key-stem 34. Each key-stem may in a like manner be connected toa second guide-arm 36, pivoted at 39.

Above the circular supports 12 13 for the type-bars is arranged acircular universal bar 50, with which the guide-link 9 of each of thetype-actions is adapted to contact in the movement of the type to theprinting posi,-

part thereof.

'and is secured at its ends thereto.

tion. This contact of the guide-link with the universal bar is sufcientto raise the latter at one side, as shown in Fig. 1 of tne drawings.Depending centrally from the universal bar is a rod 51, which isprovided with a head 52, and said rod passes loosely through a centralaperture 53 (see Fig. 20) in the universal bar or the spider 54, forminga This rod also passes through an aperture in a central hub 55, formingart of the framework of the machine. (See ig. 27.) This hub is providedwith a threaded tubular neck 55", over which the supports 12 and 13 areslipped and then clamped on the shoulder of the hub by a nut 55, thesupports 1.2 and 13 being formed with central apertures 55, Figs. 21 and22, for thepurpose of enabling them to be seated on said shoulder. Saidrod 51 is threaded at its lower end and engages with theinteriorlythreaded portion of a neck formed at the upper end of a block56, to which is pivoted at 57 the forward end of a dog-rocker 58, thatis pivotally supported upon a fixed bar 59, which extends from side toside of the frame The rocker is provided with a fixed or rigid dog 60and a loose dog 61, the loose dog 61 being pivoted at 62 (see Figs. 3and 4) and having a lateral extension 63, that carries a depending pin64. This depending pin 64 is connected to one end of a coiled spring 65,the opposite end of Which'is secured to apin 66, carried by thedog-rocker. The spring 65 tends 'normally tol maintain the. loose dog614 in the po-' sition shown in Fig. 4, and the movement of the dog bythe l,spring is limited by a fixed pin 67.

The lower end of the block 56 is threaded 'interiorly, Fig. 27, to'lreceive the upper .threaded end of a rod or pm 51a, which 1s provided atits lowermost end with a head or shoe 68, that cooperates with a roundedshoe 69, carried by a bell-crank lever" 70, that is pivoted at 71 to anarm 72, which projects forwardly from a fixed rod 73, that extendsacross the machine and is supported by the sides of the frame 1 thereof.Connected to 'the vertical arm. of the bell-crank 70 is a' draw-link 74,which has its oppositeend pivotally connected at 75 to a lever 76, thatis pivotally supported upon the rod 77 and has a forwardly-projectingarm 78, which is pivotally united at 79 to a depending stem 80 of thespace-bar 81.` 'The stem 80`of the spacebar may be notched, as show'n'at82, for the reception of a longitudinall -extending bar 83, which. isconnected to lin s or guide-arms 84, that are pivoted upon one -of therods 39, which extends from side to side of the machine. It will beobserved that the space bar or key is supported and guided in itsmovements in a similar manner to the character-keys and so that the'space-bar or the stem therefor has a substantially true lverticalmovement when operated. The motion transmitted to tle parts byvadepression of the space bar or key 81 is effective to raise the rod 51without, however, transmittin movement to the universal bar by reason othe fact that the rod 51 projects loosely throughthe central opening 53in the spider of the universal bar. A depression of the space-key will,through the lever 76, connecting-rod 74, bell-crank 7 0, and block 56,

cause the dog-carrier 58 to vibrate on its` pivot 59 and move the loosedog 61 down out of engagement with'a tooth of the feed or escapementwheel 86 and bring the xed dog loo 60 into engagement with. said wheel,as.A

shown in Figs. 2 and 4, and when the spacekey is released theA loose dogWillagain be brought IIO` engagement with the nextgy 000thl of thefeed-wheel, and the carriage will be advanced one letter-space distance,as will hereinafter more fully appear.

When the block 56 is actuated 'by` theVV space-key to effect the rockeras just described, the free end of the' rod 51 moves .upwardly throughthe aperture in the univer' sal bar or in the spideror armed portionthereof, and the universal bar remains at rest in its normal horizontalposition, as shown in Fig. 2.' When, however, a character-keyisdepressed, the universal bar will beacted upon onone side by the link 9of the particular type-bar actuated, as shown 'at Fig. 1, and by the enagement of the spider with the head 52 of t....e rod (the diametricallyopposite'portion of the spider bearing on the plate 13 as a fulcrum)lifts the rod,.and

Figs. 1, 5, ,7 seen that the rack 108,

' whereas the pinion 107 110, rthat is connected to a pinion 111, jwhich in turn meshes with a rack 112, that is carried by aball-separator 1.13, rator may be of any suitable construction A and isadapted to maintain the f friction-balls 114 in a fixed relation one to1 A y the rigid dog into engagement therewith..

en the depressed key is relieved of pressure, the parts are all restoredto their normal positions by their several springs.

Upon reference to Figs. l1 and 12 it will be seen that the feed-wheel 86is rigidly connected by a screw 87 to a hollow shaft 88, that isvertically disposed and extends through the base to the upper ortion ofthe machine. This sleeve or hol ow shaft 88 has secured thereto by ascrew 89 a clutchsection 90, which is rovided with peripheralratchet-teeth 91 and) with upwardly-extend ing ratchet-teeth 92. Theratchet-teeth 91 coperate with a spring-pressed pawl 93, pivoted at 94to the framing 1 of the machine, so that the clutch-section 90, thehollow shaft 88 and the feed-wheel 86 may rotate in but one direction,which is the direction of feed and is indicated by the arrow upon thefeed-wheel in Fig. 12.

Cooperating with the upwardly-extending teeth 92 of the clutch-section90 is a gravitypawl 95, that is pivoted at 96 to a clutch-section 97that bears at its lower end in arecess 98, Figs. 11 and 17, within therow of upwardly-extending teeth 92 on, the clutch-secq tion 90. Thedisposition of the pawl 95 is such that the clutchesections 90 and 97may rotate together when the feed-wheel and the clutch section 90connected thereto are moved in the direction of the arrow in Fig. 12.The upper edge of the clutch-section 97 is provided with teeth 99, thatcoperate with teeth on a clutch-section 100, that is secured by a screw101 to a hollow shaft .102, that surrounds the hollow shaft 88 for a pportion of its length, and both of the hollow shafts i; project throughand above'the top plate or type-ring 2 of the machine. Surrounding thehollow shaft 102 is a coiled spring 104,

which bears at its upper end against a cylindrical housing 105, thatsurrounds the spring and is rigidly connected to rotate with the clutch97 by a screw 105x. The other end of i'. the spring 104 bears againstthe top of the clutch-section 100, and the expansion-spring normallymaintains the teeth of the various "l clutch-sections in engagement. Thehollow shaft 102 carries at its uppe` end a pinion 106, and just belowthe pinion 106 is secured a second pinion 107. Upon reference to 7, and8 of the drawings it will be pinion 106 meshes with a feedthat iscarried by the carriage 109, meshes with a gear This sepalooseantianother in the fixed raceways `115 during the travel of the carriagefrom end to end of the machine. It willbe understood that a rotation ofthe hollow shaft 102 will cause a rotation of the feed-pinion 106 andthe pinion 107, so that the ball-separator and carriage will be movedwhen the escapement mechanism is operated to effect a rotation .of thehollow shaft. It should be understood that a suitable spring-drum (notshown) is connected to the carriage to move it in the direction of itsfeed, or from right to left, when' the escapement mechanism is operated,as in prior machines.

Secured to the carriage 109.and extending longitudinallythereof from endto end is a bar 116, Figs. and 6, which extends beneath the pinion 106andl is provided at its ends with inclined slots 117, into which projectpins 118, that are secured to the carriage. The bar 116 is likewiseprovided with an upwardly-extending finger 119, that projects into anelongated slot 120 of a lever 121, that is pivoted at 122 to thecarriage and has an arm 123, that cooperates with a lever 124, pivotedat 125, Fig. 28, t0 the platen-frame 126. This lever 124 is provided atits forward end with a finger-key 127, and when the lever 123 isvibrated on its pivot through an actuation of the iinger-piece 127 thebar 116 will bev elevated by reason of the pin and inclined slotconnection provided therefor. This upward movement of the bar 116 willcause the pinions 106 1.07 to be elevated, but not sufiiciently todisengage them from their racks. A like elevation of the hollow shaft102 is produced, which eifects an upward movement of the clutch-section100 carried thereby to disengage it from the coperating, clutch-section97, (see Fig. 8,) when the carriage is then free to be moved in eitherdirection. In this movement of the shaft 102 the spring 104 iscompressed, and when the finger-key 127 is released the parts vwill beimmediately restored to the normal or engagingposition. (Shown in Fig. 7of the drawings.) Should the carriage be moved from left to rightwithout disengaging the clutch; sections by means of the hand-operatedrelease-key 127, the clutch-section 100, ,the spring 104, thecylindrical housing 105, which is secured to the clutch-section 97,and'. the clutch-section 97 will be rotated together withouttransmitting movement to the feed.'- wheel 86 or to the otherclutchsections, because at this time the pawl 95 on the clutch member 97will ride freely over the teeth 92 on the clutch-section 90, and henceno movement will be transmitted to the clutch-section 90 or theescapement-wheel 86. When, however, 'the carriage-driving spring (notshown) is rendered effective to move the carriage in the direction ofits feed, or, in other words, when theescapement mechanism is* operated,the tension of, the carriage-spring tween the carriage and the shaft102, and by this movement 'the carriage 'will cause thecauses the hollowshaft 102 to be rotated through the rack-and-pinion connectionbeclutch-section' 100, the clutch-section 97, the

lcoiled spring 104, `the cylindrical housing 105, the clutch-section 90,and the feed-y Wheel 86 to be rotated, and in" this movement of theparts the pawl 95 is effective'to cause IO` the clutch-sections 97 and90 to rotate to- 'This movement of the carriage causes a rotation of thecoiled spring 104 and the lcylindrical housing therefor with the shaft102 and the cooperating clutch-secclutch-sectlons in operativeengagement,

i posed feedtions, and for this reason the tension of the spring 104does notretard the movement of thencarriage or the escapement mechanism,althiigh it exerts a pressure to maintain th an this constructionconstitutes a feature of the present invention.

through the horizontally-disheel. 86 and the vertically-dis posed hollowshafts 88 and 102 is a shaft or rod 128, which is guided by 'but isfreely movable-within the hollow shaft 88. The upper end of this rod 128has rigidly secured thereto anarm 129, to which is pivoted at 130 anabutment or stop 131. The movement of this abutment 131 is limited byafinger 132, Fi 19,

Extending v arm'129, and t is abutment 131 is normally maintainedagainst the finger 132 by a spring 133, which bears at one lend againstthe abutment and at its opposite end against the arm 129. The abutment131 normally projects in to the path of a cooperating abutment towardthe left.

end of this arm 138 carries a depending pin 139, which is adapted toproject through an elongated opening or slot 140, Fig. 26, in abell-crank line-lock lever 141', which is pivoted at 142 to the fixedbar 73, that extends fro-m'si de to side of the machine. This bellcrankline-locking lever is maintained normally in the disengaged position bya contractile spring 144, Figs.' 9 and 10, which is secured at one vendto a pin 145 and at the other end at 146 to lone arm of thelockinglever. The terminal ofthe arm 147 of the line-locking lever isadapted to project above the shoe 68, that is operatively connected tothe dog-rocker 58. 134 is adjusted to The traveling abutment the properposition on the desired to lock the printsenese axis. This slightturning movement of the downward which projects from the j ing andfeeding mechanisms against operation at the end of a line.

When the carriage is movedin the direction of its letter-feed, or fromright to left, and the end ofthe line as determined by the adjustment ofthe abutment 134 is reached, said abutment will be brought into contactwith the abutment 131 of the line-lock mechanism, and a slight furthermovement of the carriage will cause the abutment 131 to move therewith,thus turning the shaft 128 on its shaft 128 is effective to move thelocking-lever 141 from the position shown at Fig. 9 to that illustratedin Fig. 10. When the locking-lever is in the position shown in Fig.10,the shoe 68 is prevented from upward movement, so that the universal baror ring 50, which is operatively connected thereto, and thedog-rockeru58, which is likewise operatively connected thereto, will belocked against movement lby the finger-keys or space-bar, and at thistime no further writing can take place. Should the operator desiretowrite one or more characters, to insert a hyphen, or ,complete a word,the abutment 131 may be moved out of the path of itsr eooperatingabutment 134 to permit a further feed movement of the carriage and torelease the line-lock. This is accomplished by the depression of aseparate finger-key that is preferably located at the keyboard of themachine. This finger-key is connected and mounted in the same mannerasthe other finger-keys at the keyboard and is adapted to transmit motionthrough a draw-link. 149 (see Figs. 1, 2, and 11) to a lever or cam 150,to which the draw-link is connected atl 5 1. This lever or cam 1 50extends beneath the lower endof the shaft 128, so that when theline-lock release-key' is depressed the lever 150 will be moved aroundits pivot 152, thus causing the shaft 128 tobe movedupwardly orin thedirection of its length, as shown in Fig. 7 of the drawings. Thismovement of the shaft '128 car.- ries with it the abutment 131, which atthis time' is raised toa position where it is out of the path of thecooperating abutment 134 on the carriage. As soon as the abutment 131has been released from its coperatin abut-v ment 134 in the mannerdescribed t e tension of the spring 144 is eective to restoreV theline-'lock lever 147'and the parts connected therewith to the normal orunlocking position represented in Fig. 9, andthe printin and the spacingmechanisms 'may be operated as b efore to finish out the line. Theabutment 134 having moved to the leftof its coperating abutment 131, itis necessarythat the abutment 134 shall be able to freely pass theabutment 131 in the movement of the carriage from left to right. This isaccomplished by the beveled face 135 vupon the abutment 134,l which onthe return A'movement of the carriage to the righticontacts with theabutment 131 and moves it upwardly about its hinge-pin 130, and thispermits the abutment 134 to pass under and by the abutment 131, thespring 133 serving to restore the abutment 131 to its normal position`after it has been released by the abutment 134.

Referring particularly to Figs. 28, 29, 30, 31, 32, and33 of thedrawings, it will be seen that the platen-frame 126 carriesrearwardlyprojecting arms 153, which constitute bearings for thereception of movable lockingplungers 154, each of which is provided atits outer end with a hand-operated head 155, thatV is apertured for thereception of an eX- ansion-spring 156, which bears against the head atone end and against the bottom or inner wall of a recessed portion 157,formed in an extension of the platen-frame pintle or hinge-pin, andwhich extension is fast or tight in the arm 153. The inner end of eachof the locking-plungers 1511 is provided with an enlarged portion orcylindrical lookinghead 158, that is adapted to be seated in a circularrecess 159 in an open bearing 160, that extends upwardly from thecarriage 109. The platen-frame intle or iinger-pin 160@l turns in theopen bearing 160 when the platen-frame is swung up to inspect or correctthe work. The plunger 154 passes through said pintle and takes a bearingtherein as well as in the 4extended portion of said pintle, which isfast in thearm 153. vWhen the locking-head 15S at each side is seated,as shown in Fig. 32, the platen-framecannot be detached from thecarriage, because the diameter of each of s aid heads is greater thanthe slot of the open bearing 160; but when the heads 158 are pressedinwardly, as shown in Fig. 33, the pintles 160EL may be lifted out fromthe open'bearings and the platen-frame i,

thus detached. By these means latenframes of diilerent sizes may bereadi y substituted one for another, or the platenframe may be readilyremoved for the purpose of repairing or adjusting any of the partsconnected thereto or which operate therebelow.

The platen-frame 126 carries a platen 161, which is provided with theusual fingerwlieel 162 at the left-hand end thereof, the platen beingadapted to rotate in suitable bearings in the platen-frame. Cooperatingwith the platen 16] is a paper-feed roller 163, the shaft of which restsin open-slot bearings in the arms 166, one being provided at each end ofthe shaft. These arms or links 166 are pivoted to a cross-bar 167 of theplatenframe, and to each arm is connected one end of a coiled spring169, that surrounds the cross-'bar 167.. lhe opposite end 170 of eachspring is connec'nd to means (not shown) contained withiir a housing 171and by which an adjustment of the tension of each spring is afforded.The arm 166, which supports the left-hand end of the feed-roller, hasrigidly connected thereto a forwardly-extending arm 178 which isfashioned lnto a finger-key 179 at its forward end. By depressingthedinger key or piece 179 the paper-feed roller 163 will be forced outof contact with the platen or the paper thereon, andthe paper may beeasily adjusted to any desired position on the platen. Each of the arms166 supports a'spring-arm 180, Fig. 30, and the lower ends of these armsare connected by a paper-blade 181, which extends substantially throuhout the length of the platen and normal y presses thereagainst.

,This paper-blade may be adjusted with relation to the platen by screws182, which eX- tend through elongated slots in the spring- 'arms 180 tosecure them in place. The aper-blade being connected to the feed-rolercarrying arms, it will be understood that a downward movement of thefinger-key 179 operates to move both the feed-roller and the paper-bladeaway from the platen, in order that the paper ymay be freely introducedand adjusted on the platen.

Cooperating with the peripheral teeth 205 on the feed-wheel is a detentor pressureroller 216, Figs. 28 and 29, which is mounted m bearings upona spring 217, that is secured to the platen-frame at 218. A line-spacingpawl 219 coperates with the teeth 206 on the side of the Wheel and isactuated by a rock-shaft 220, that turns in hearings 221 on theplaten-frame. The forward end of the rock-shaft has secured thereto aiinger-piece 222, by which the rock-shaft may be turned to actuate theline-spacing pawl 219, Iand thus effect a line-feed `movement of theplaten, as common heretofore in Yost machines.

Various features herein shown and described which relate to the typeaction constitute no part of my invention, but are the invention ofArthur l/V. Smith. In this connection it should be understood thatinstead of the type action shown and described the ordinary Yost or anysuitable t e action may be employed. It should lewise be .understoodthat various features of the invention may be used in dnerent charactersof type-writing machines from that shown,

and that to this end numerous changes may be made without departing fromthe spirit of my invention.
